We will try some fast text modes this weekend on The Mighty KBC, to see if they can survive the rigours of shortwave.

This will be during the North America broadcast at 0000-0200 UTC 20 January on 9450 khz. At about 0130 UTC, 4XPSK63R will be centered on 1000 Hz and MFSK64 centered on 2000 Hz. (For 4XPSK63R, use Fldigi 3.21.65 or newer: OpMode > PSKR > MultiCarrier > 4XPSK63R.) At just before 0200 UTC, MT63-2000 (long interleave) will be centered on 1500 Hz, and PSKR250 on 2800 Hz. This will be an Flmsg formatted transmission, with html. Fldigi and Flmsg can be downloaded from www.w1hkj.com.
